Corinth was famous for its orators and its prosperity… but also for its immorality. There Paul preaches the cross, a madness for the Greeks, who are looking for a worldly wisdom to turn away from God… But also a power, the true wisdom of God, ” for the wisdom of the world it is a unique and unimaginable event: the incarnation of the Word, of the Word of God, of Jesus Christ” (Karl Barth)
